Roundtree is listed at running back, but will start at defensive end, a position he may play in the fall at Maryland.

"He will be rushing the passer and should make a lot of plays," said Maryland all-star coach Ben Wright (Thomas Johnson). "He has lots of potential. He's big, strong and fast."

Look for City's Smith to play a lot of wide receiver, even though he'll start at defensive back. According to Wright, Smith, at 6 feet 4, matches up well against Pennsylvania's starting receivers, both listed at 6-4. Singfield will also start at defensive back.

Dunbar's Williams, an All-Metro linebacker, will line up at tight end for the first time.

"He's very athletic and has good hands for a tight end," said Wright.

On the offensive and defensive lines, the team is undersized.

"We're a little more hampered in terms of linemen," Wright said. "We'll be going up against guys who weigh 350, even 380 pounds."

Georgalas, who will start, weighs 225 pounds.

Wright said that's a problem he can work around. "We're quicker [than Pennsylvania] and speed will beat size any time," he said. "We can't run them over, obviously."

Coaches selected the players for the Maryland team after they were nominated by the media. "We picked kids for this game that can play both ways, to give us more depth," Wright said. "Almost every kid on the roster can play both ways."

This game is the brainchild of Jim Stephenson, the Mason-Dixon Classic managing director. He is a retiree from California who worked with Shriners Hospitals for Children. When he moved from California to Waynesboro, Pa., last year, he said, he was surprised that no game existed between the two states.

"I saw a lot of talent left on the board," Stephenson said. "There was so much talent not playing in all-star games."

This will be the second all-star game for Maryland this summer. Last month, Maryland defeated Northern Virginia in the Chesapeake Classic, 29-20. Maryland has participated in the Chesapeake Classic since 1993.
